问题 Update: Since this is unanswered, I'm changing the question slightly. Comments on the post on Dean's blog linked below indicate this technique does not work in Safari. My question now is: does the technique described below work* in modern browsers, and in particular can someone confirm whether it works in Safari? Here's a more recent blog post. It says at one point: Sandboxed natives ... are supported in a variety of browsers, including ... Safari 2.0+ ...but later says that the iframe

由 你说的曾经没有我的故事 提交于 2020-01-11 13:14:20
问题 I am developing a site which heavily uses jquery (UI) for providing a good user experience. For some (stupid) reason parts of this site are shown within an iframe and there also is a button for refreshing the iframe to get the latest data from the server. The problem is that each time when refreshing the iframe the memory usage increases leading to serious memory problems after some time (Tested in IE8 & 9). But this occurs only if the jquery library is loaded. This behaviour can be seen best

问题 I'm building a webpage using React which means I can't manipulate the DOM directly. I've tried reloading my iframe by updating the url state but that doesn't seem to reload the page.

Trick To Get Qt QWebView Bridge Accessible from Webkit IFRAME (Local Pages)

由 偶尔善良 提交于 2020-01-11 10:43:38
问题 My Qt C++ (Qt 5.5) application uses a QWebView widget. After a lot of confusion and hard work, I have managed to get the QtWebKit Bridge technique to work and now have my Webkit document (local pages, no web server) to be able to call the C++ functions.

Differences in using <iframe> and <embed> for displaying SVG and scripting

由 ≡放荡痞女 提交于 2020-01-11 08:34:08

I'm not entirely sure if I should use the embed tag or an iframe for displaying the SVG here are my doubts regarding SVG and scripting: Whats the difference
